As presented Nov 7, 2017 at the OpenStack Summit Sydney for this session https://www.openstack.org/summit/sydney-2017/summit-schedule/events/20421/opencontrail-from-a-to-b-front-to-back-top-to-bottom-past-to-present-soup-to-nuts

1. OpenContrail Overview
Nov 7, 2017

2. VISION
• OpenContrail seeks to become a ubiquitous global network fabric that is agnostic and extends
across all cloud infrastructure.
• It will provide a single point of control, visibility, and management globally for all networks and
network security.
• It will become the most broadly adopted and highest quality SDN overlay technology available.

3. MISSION
Build the world’s most ubiquitous, easy-to-use, scalable, secure, and cloud-grade SDN stack,
providing a network fabric connecting all environments, all clouds, all people.

• Clusters are federated to
extend virtual networks

15. INSTALLATION
• Ansible playbook to flexibly deploy OpenContrail / Contrail binaries
• Helm charts to easily operate OpenContrail components on Kubernetes
• Install-time option with OpenShift to deploy with OpenContrail
• OpenContrail binaries available on DockerHub and we’re improving CI/CD
• Commercial integrations into lifecycle tools like RH OpenStack Director

16. USER EXPERIENCE
• REST API
• HTTPS authentication and
role-based authorization
• Used for GUI
• Used for declarative
configurations as code
• Generated from data model
